Welcome to the best Duramax forum on the net and congrats on your first diesel truck.

There are lots of great additives out there. Most use Power Service (white bottle for winter, grey bottle for summer) because you can easily get it at just about any store. There are other ones you can get on line if you have time to wait for it. Just be sure the additive doesn't have alcohol in it.
